In a post to her official blog, the reality star said: "As I'm sure you all know by now, I got Punk'd! I was so excited for my girls' night with Miley and Kelly, and let me just say, they got me really good.

"I thought the show was cancelled and I had no idea they were bringing it back so I was NOT expecting to be Punk'd. (sic)"

Kardashian's sister Kim Kardashian had earlier told Twitter followers that the star had kept her appearance on the show a secret, writing: "I can't believe @KhloeKardashian never told anyone in the fam she got Punk'd!!!! I can't wait to see this episode! (sic)"

Punk'd's new series will feature a different guest host each week, with Justin Bieber, Kellan Lutz, Bam Margera and Dax Shepard already confirmed as among the other pranksters.

Ashton Kutcher created the hidden camera show with Jason Goldberg and served as the original host from 2003 to 2007.
